all progress lost

everything just gone in the game
the leaderboards still show my progress, however i start forza horizon 2 and it just starts me at the start of the game with nothing. 700 hours, 334 cars owned, and 12,943,126 xp all down the drain. I have tried everything but nothing works. please someone help.

Nothing can be done.
You will just have to start over again.
All your online and stats will still count but cars and credits will have to be earnt or purchased again.
A killer I know but this happened to me also

test please disregard!
